When did the half-step/whole-step modulation in the middle of a song become popular?

The modulation you describe is often mockingly called the "Truck Driver Gear Change". As you say, it is quite often used, to the point of being cliche. It has it's own page on TVTropes. At one time, ...

With modern electronic technology is temperament unnecessary?

In principle, the answer is yes, with software instruments it is feasible to (re-)set the tuning so that you can realize music with modulation that stays in just intonation across these changes. The ...

modulating from G major to G# major

Any readers may thank you more if the new key becomes Ab. Ab has only 4 flats in it, whereas G# has 8 sharps. The simplest, which always works, pretty well whichever key you're changing into, is to ...

With modern electronic technology is temperament unnecessary?

You cannot even realize "just temperament" reliably when you are working with continuous-tone instruments like singers and trombones. Take a look at even something as old as J.S. Bach's mass in B ...

Chopin Polonaise in Ab major, op 53 change in key

You're exactly right! It's technically a motion to ♭VI, which would be F♭ major. But in order to make it easier to read, he spells it in E major (♯V). F♭ isn't in A♭ major, but it is in A♭ minor; ...

Can the same song be written in a minor key and major key with the progression written differently?

The scale/chords are good clues to the key of a song, but at least as important is the tonal center. That's not as easy to define but generally it's where the song comes back to a place of less ...

With modern electronic technology is temperament unnecessary?

It's a bit more complicated than may appear at first glance. Within a single key, if Just Intonation makes the I,IV, and V chords all (4,5,6) ratios, the ii chord will be off. The other question is ...

Great question; this is a particularly clever part of music theory! Here's a nice little example in F major; it's just a I--V7--I progression with a little cadential six-four thrown in there just ...

What's the exact difference between modulation, key change and tonicisation?

I think your intuition is mostly correct when it comes to modulation. I would make only one small adjustment: most scholarship tends to view a change in tonic as different from a change in mode. In ...

What is the musical term for a song that uses a higher key for its last chorus?

Actually none of these are examples of singing in a higher octave, they are examples of “modulation”, a changing of key, usually to a key that is a semitone to a few semitones higher than the original....

Why isn't there a closely related key to C minor that has D as tonic?

Closely related keys are keys with key signatures within one accidental of each other. Find the number of accidentals in the given key signature, then find the keys that have that same number (and ...

How can I explain/understand a flattened 2nd in a minor melody

Those flattened 2nd scale degrees could point to tonicization of or temporary modulation to the subdominant (e.g. if ^1-^♭2-^1-^4 is harmonized as i-VI/iv-V/iv-iv). But those flattened 2nd scale ...

If there is a double sharp on a note, does that mean the piece has modulated?

Let's restate your question generally as: "does an accidental mean the piece has modulated?" An accidental in a passage does not necessarily mean the music has modulated. Sometimes chromatic ...

How to modulate very smoothly and stealthily from major to minor?

Within a minimalist sort of setting, one approach I might take would be to boil things down to just the root or root and fifth. If you have a long enough period of time where you don't have a third ...

If parallel keys aren't closely related, then why are they so easy to get to?

Closely related keys are keys that have at most one accidental difference. So the set of notes inside the key are almost identical (or identical in the case of relative major/minor keys). You can get ...

What type of modulation goes from D♭ to A?

By definition, a modulation must reach a cadence in the new key. Since there is no cadence on B♭♭ here, it's technically incorrect to call this a modulation. Instead, he's simply using a B♭♭ chord ...

Why does G-Major work well within a C-Minor progression?

The G major chord is the "usual" dominant in the key of C minor. The harmonic point is the half-step approach to the note C from B. It is extremely common. As a side note, often, when a ...

There are two broad categories. Modulation to closely related keys - 'keeping it in the family'. And modulation to more distant keys for contrast. The first kind include modulation to the dominant, ...

Harmonic analysis of "Walk this Way" by Aerosmith
